7+ years of progressive experience in systems engineering.

Responsibilities

Provide principal-level technical leadership for resilient, secure, scalable, and cost-efficient platforms across Azure, AWS, Kubernetes, and hybrid-cloud environments.
Lead FinOps and infrastructure optimization capabilities, including cost allocation, showback, anomaly detection, forecasting, rightsizing, workload scheduling, commitment optimization, waste reduction, and validated savings realization.
Develop policy-driven, closed-loop optimization workflows that move recommendations through identification, application-owner engagement, approval, ServiceNow change control, execution, validation, evidence capture, and reporting.
Apply an automation-by-default approach using Python, PowerShell, Bash, REST APIs, Azure Functions, Power Automate, and event-driven services to reduce manual handoffs and operational toil.
Design practical generative AI, AI-fueled coding, and agentic automation solutions for engineering operations, cost analysis, anomaly investigation, remediation guidance, executive reporting, knowledge retrieval, and decision support.
Establish cloud-governance guardrails, policy-as-code controls, exception processes, auditability, and risk-based automation patterns aligned with security, architecture, compliance, and change-management requirements.
Engineer secure identity and authorization models using role-based access control, managed identities, service principals, privileged identity management, just-in-time access, least privilege, and time-bound permissions.
Integrate optimization and automation capabilities with Terraform, GitHub, Azure DevOps, CI/CD pipelines, ServiceNow, monitoring platforms, cost-management tools, and enterprise data sources while preventing configuration drift.
Advance reliability engineering practices, including observability, service-level objectives, capacity management, performance analysis, incident prevention, operational readiness, post-change validation, rollback planning, and continuous improvement.
Build executive dashboards and operational scorecards that communicate cloud spend, reliability, automation coverage, optimization pipeline health, risk, realized savings, and customer or business outcomes.
Lead proofs of concept, production readiness, phased adoption, and complex technical issue resolution in partnership with internal teams and strategic vendors.
Mentor engineers, create reusable reference architectures and standards, and influence priorities across Reliability, FinOps, Security, Architecture, Finance, Operations, and application teams.
Demonstrate AT&T leadership behaviors by serving customers first, moving faster, acting boldly, winning as one, and developing talent.
